The number of subsets that can be created from the set {1, 2, 3} is:
a.3
b.6
c.7
d.8

The correct option is d.

Step-by-step explanation:

The given set is {1, 2, 3}.

If a set has n elements , then the formula for number of subsets is

Number of subsets =

In the given set the number of elements is 3. So the number of subsets is

Number of subsets =

The number of subsets is 8. The subsets are

1. {}

2. {1}

3. {2}

4. {3}

5. {1,2}

6. {1,3}

7. {2,3}

8. {1,2,3}

Therefore the correct option is d.
